1:2 - For every green apple, you have 2 red apples.

Simples.
3. that's it, I'm thinking maybe I have to explain more

How about if we are booked to do a job worth 150 but because I am the boss and twice as qualified I get twice as much so we share the cash 2:1 so using ratio a good way of sharing fairly

If you have a set amount of items, lets say 200 apples, and 150 are green while 50 are red, then this ratio is 150:50 (green to red) [and the numbers add up to the quantity] so just explain to the students that this can be simplified into a 3:1 ratio, not sure how you'd explain the simplification lol.

Perhaps 200=50R+150G (where red and green denote colours)
4=R+3G, so the ratio is 3:1

Last time I had anything to do with Y7 was 6 years ago so I dont even remember how much they know lol.
6. that's great thank you
7. would the objective be :
